STORAGE-BATTERY LOCOMOTIVE.

i Appiication filed April 5, 1917. 'serial No. 159,965.

T0 all whom t may concern kBe it known that I, GEORGE H. F. HOLY,

Aa citizenof the UnitedStates, and a yresidentpf Pittsburgh, in the county otAlleglieny andY Statek of Pennsylvania, have invented 1a new and useful Improvement in lStorage-.Battery Locomotives, lof ,which the following is a speciiication.

My inventionv relates to locomotives and particularly to) storage-battery locomotives for service. in mines.

. One object of .my invention is to yprovide a locomotive of low height `which shall besimple, rugged and economical inconstruction and yeilicient and reliable in opera- OD. i l

Another` object of my invention is to provide a Vlocomotive vofthe above indicated character ythat shall be provided with two bodies having propelling trucks;y a storage battery mounted von one of sa-idlbodies, and a pivotal connection between thebodies and trucksthatis disposed so as' to support a 'portion of the weight of the section con rtaining the storage battery on the body and truck associated therewith.

A further object of my invention is to .provide arstorage-battery locomotive that shall be provided with twotwo-wheelfpropellingtruclrs, a str )rager battery mounted on,y and disposed between,.the propelling wheels of said ytrucks and resilient meansv alinement with each other.

Locomotives intended for service in mines should -be of minimum height kand rugged in construction in order to meet the re'- quirements of the service demanded oi. them..

In many cases, it isv impracticable to ,operate a locomotive that is suppliedwith energy from a trolleyconductor and, insuch cases,l a flocomotiveprovided with a cable and a reel or a ,storage-battery'locomotive is resortedto. Thesto,ragebattery locomotive is the only practical solution of the problemwhere the. locomotive is operated However, va storage battery which will serve for propelling a locomotive is of relatively great weight and takes upconsiderable room. Thus, it' is essential to'have the storage battery conveniently disposed on the locomotive soas not -topincrease the heightof `'the same and to equitably distribute the weight of these-me *Y on the various wheels of the locomotive.

kIn ka-.jlow-height storagebattery f locomotive constructed in accordance with my invention, the weight of the battery 1s equitably distributed on the various pairs of as not to increasethe height ofthe loco motive orto interfere with the apparatus for controlling the same, 4In the accom- Fig. 2 is a side elevational view, partially invsection, of the locomotive illustrated in Fig.l lk; Fig. 3 is aplan view of a locomo-y ,tivey embodying a modification of my inven-y tion; and Fig. '4 is a side elevational View of the locomotivesliown in Fig. 3. y

Referring to Figs. l and 2 of the draw.'- ing a locomotive 1 embodies two low-height bodies 3 and 4 constituting the similar end sect-ions of the locomotive, which are respectively provided with two-wheel supporting trucks having pairs of driving wheels 5 and -6,:and acentral section 7 which is respectively connected to the bodies and-.4 by means of pivotal connections 8 and 9. The

truclrof the body 3is provided with a mo-' tor 10 rwhich is connected to the pair of drivingywheels 5 by means of a pinion l1 and a gear wheel 12, and the truck of the body 4 is provided with a motor 13- which is connected .to the pair of driving wheels 6 by means of a vpinion 14Kand a gear wheel 15.

wheels of the locomotive and is so disposed rfhe central section 7 embodies a body porb l tion 16 for `supporting the storage battery which supplies energy tothe locomotive and two end projections 8 and 9a which project over the bodies-3 and 4.

. 'A projection y17', which extends from the body 4, is provided with two vertical ribs l A18 and 19 and a horizontal rib 20. The body 3 is provided. with a similar projection 21 which embodies two vertical ribs 22 and 23 and a horizontal rib. 24. Four springs, 25,

trucks and the bodies 3`r and 4 and the central section 7 in horizontal alinement with each other. A spring 29 is disposed between the rib 2O and the projection 9l of the central section 7 and a similar spring 29a is disposed between the cross-piece ,30 on the central section 7 and the rib 2() for exerting a force tending to maintain the end section or body 4 and (its truck and the central vsection 7 in vertical alinenient with each other. A spring 3l is disposed between the rib 24 and the projection 8?. and a spring 32 is disposed between the cross-piece 3S on the centralsection 7 and the rib 24 tor exerting a force tending to maintain the end section or body 3 and its truck andthe central section 7 'in vertical alinement with each other.

Although springs 25, 26, 27, 2S, 29, 29, 3l and 32 are provided Ator exerting a force tending to maintain the two trucks and the bodies or end sections 3 and 4 and the central section 7 in horizontal and vertical `alinement with each other, the pivotal con-v nections 8 and 9 may be disposed relative to the driving 'wheels 5 and 6 so as to maintain the various parts in alinement with each other.

In referring to Figs. S and 4, reference characters are used which correspond to those serving to designate the various parts ot the locomotive illustrated in Figs. l and V2. In the modification illustrated in Figs.

ment relative to each other by means of the lsprings 27, 28, 3l and 32.
